The Capture, Preparation, and Preservation of Specimens 
vided with circular openings of various sizes, into which the larvaf 
skin is introduced (Fig. 6 f). 
“ A less commendable method of preserving larvae is to place 
them in alcohol. The larvae should be tied up in sacks of light 
gauze netting, and a label of tough paper, with the date and 
locality of capture, and the name, if known, written with a lead- 
pencil, should be attached to each such little sack. Do not use 
ink on labels to be immersed, but a hard lead-pencil. Alcoholic 
specimens are liable to become shriveled and discolored, and 
are not nearly as valuable as well-inflated and dried skins.

“ When the skins have been inflated they may be mounted 
readily by being placed upon wires wrapped with green silk, or 
upon annealed aluminium wire. The wires are bent and twisted 
together for a short distance and then made to diverge. The 
diverging ends are pressed together, a little shellac is placed upon 
their tips, and they are then inserted into the opening at the anal
